BEAN-SEPARATOR.

To all whom it may concern:

Be it known that I, FREDERICK C. Berra, a citizen of the United States,residing at lniiddleport, in the county of Niagara and State of NewYork, have invented new and useful Improvements in Bean-Separators, ofwhich the following is a specification.

This invention relates to bean separators and pickers, the object of theinvention being to provide a simple and reliable machine for effecting aseparation between good and defective beans and the like and pickingfrom the good beans any adhering inaterial, thereby providing for thedischarge of the good product from the machine in a clean and marketablecondition.

While the invention will be described as adapted for the purpose ofpicking and separating beans, it will be obvious as the de scriptionproceeds that the machine is also adapted to operate with equally goodeffect on other products such as peas, wheat or grain of any kind.

lVith the above and other objects in View the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed.

In the accompanying drawings: Figure 1 is an elevation of a separatingand picking machine constructed in accordance with the presentinvention. Fig. 2 is a plan view thereof partly broken away to show themeans for actuating the picking rolls. Fig. 3 is a vertical longitudinalsection through the machine on the line S3 of Fig. 2. Fig. 4 is avertical cross section through the same on the line 4- l of Fig. 3. Fig.5 is a detail vertical section showing the means for actuating thepicking rolls. Fig. 6 is a detail elevation showing the arrangement ofbearings for the picking rolls. Fig. 7 is a detail vertical longitudinalsection on the line 77 of Fig. 4.

The frame of the machine contemplated in this invention is shown forconvenience as comprising corner uprights or posts 1, top and bottomlongitudinal beams 2 and 3 respectively and top and bottom cross beams Land 5 respectively.

In addition to the parts above referred to, the frame comprises thelongitudinal bearing rails 6 and 7 located at different elevations andextending parallel to each other and having journaled therein the shaftsof a Specification of Letters Patent. Application filed February 13,1909.

pair of belt carrying rollers S and 9 located at opposite ends of themachine and inclined from end to end as indicated in Fig. 4. A carrierbelt 10 travels around the rollers S and 9 and is laterally inclined asshown in Fig. 4-. The shaft of one of the rollers is extended as shownat 11 and has mounted thereon a driving pulley 12 adapted to re ceive adriving belt fr iii any suitable motive power whereby motion is impartedto the belt 10 and to the remainder of the machine as will hereinafterappear.

Arranged in a horizontal series above the top run of the belt 10 arepicking rolls 13 mounted in bearings on the bearing rails 6 and 7 andinclined to correspond with the belt 10 and so as to operate in parallelrelation thereto and close to the top run of the belt as shown in Fig.3. Located between the two runs of the belt is a correspondinghorizontal series of bearing rolls 1% which support the top run of thebelt and sustain the pressure transmitted by the picking rolls 1?). Theshafts 15 of the picking rolls have mounted on the ends thereof groovedpulleys 16 around which pass belts 17 which extend downward aroundcorresponding grooved pulleys 18 on a common transmission shaft 19extending lengthwise of the machine frame and mounted in suitablebearings one of which is shown at 20. The shaft 19 is driven from theshaft 11 by means of bevel or miter gears 21, said gears being soproportioned that the picking rolls are driven at approximately the samesurface speed as the carrier belt 10.

22 designates the main hopper for feeding the beans downward upon thecarrier belt. This hopper is provided with a plurality of downwardlyextending spouts 23 which dis charge the beans just in advance of eachof the picking rolls 13 as shown in Fig. 3 and just behind a series ofcheck rails 24 in the form of slats disposed edgewise vertically andextending at an inclination corresponding with the lateral inclinationof the car rier belt across the machine between the bearing rolls 7. Thebeans are thus discharged upon the belt 10 just in front of the pickingrolls which act to pick and clean the good beans and direct the same offthe lower edge of the belt while the bad beans are crushed and passedunder the rolls until they are checked by the bars or rails 24 whichserve to direct the bad beans off the lower edge of the belt.

25 designates the main receiving trough which extends practically theentire length of the frame and is inclined from its opposite endsdownward toward its center where it terminates in a discharge nozzle 26.This trough 25 is arranged to receive the good beans. The defective orrefuse beans are received in an inclined gutter 27 which extendslengthwise ofthe machine frame and is provided with a number ofupstanding nozzles 28 which intersect the main receiving trough 25 asshown in Figs. 4 and 7 and are arranged directly in line with the checkbars 24. The gutter 27 communicates at its lower end with a dischargespout 29. Any suitable receptacles may be placed beneath the dischargespouts 26 and 29.

It will be seen that the beans or the like, after being deposited on theendless carrier belt, are subjected to the picking action of the rolls13 which revolve in the same direction and at the same surface speed asthe endless carrier belt, the result being that the defective beans arecarried under the picking rolls and between said rolls and the top runof the endless carrier belt, and against the check bars which direct thesaid defective beans into the nozzles 28. The good beans are held backby the picking rolls and subjected to the picking and cleaning action ofsaid rolls which operate to free the beans from any adhering matter, thegood beans gravitating or rolling down and off the lower edge of thecarrier belt into the main receiving trough 25 and outward through thedischarge spout 26 thereof.

1. A. machine of the class described, COIIlprising a laterally inclinedendless carrier belt, picking rolls extending transversely across saidbelt and correspondingly inclined from end to end, check bars arrangedat one side of the picking rolls and extending parallel thereto, aseries of supporting rolls extending parallel to the picking rolls andarranged beneath the picking rolls and between the top and bottom runsof the belt, and means for simultaneously driving the belt and pickingrolls at a substantially equal surface speed.

2. A machine of the class described, comprising a laterally inclinedendless carrier belt, a series of inclined picking rolls ex.-

tending transversely across the belt and in parallel relation thereto,check rails extending across the belt and arranged close to the belt andparallel to the picking rolls, a corresponding series of supportin rollsextending parallel to the picking rolls and arranged beneath the sameand between the top and bottom runs of the belt, means forsimultaneously driving the belt and picking rolls at a substantiallyequal surface-speed, a receiving trough arranged to receive the goodproduct from the lower edge of the belt, and a refuse gutter havingupstanding nozzles intersecting the receiving trough and adapted toreceive the defective beans and refuse directed thereto by the checkbars.

In testimony whereof I afliX my signature in presence of two witnesses.
